Hi,
I'm working on a Redshift server and I have a simple formula to translate our campaign code to corresponding text using the first letter of the code in a Prepare recipe
However I can't use SQL engine to compute the formula.
I see that we can write a custom SQL translation but I don't know what it expects (a full select from code or just some parts?)
My formula is below, thanks a lot for your help.
And I have the same problem using the Now() function in a formula to retrieve today date?
if (substring(first_promo_code,0,1) == "A","Autopro", if (substring(first_promo_code,0,1) == "B","Couponning dans autre revue", if (substring(first_promo_code,0,1) == "E","Encarts", if (substring(first_promo_code,0,1) == "F","Opérations spéciales courtes durées", if (substring(first_promo_code,0,1) == "I","Internet", if (substring(first_promo_code,0,1) == "M","Mailing", if (substring(first_promo_code,0,1) == "N","Parrainage", if (substring(first_promo_code,0,1) == "H","Délégués religieux", if (substring(first_promo_code,0,1) == "U","Délégués jeunesse/Réseau jeunesse", if (substring(first_promo_code,0,1) == "W","Export", if (substring(first_promo_code,0,1) == "Z","Divers", if (substring(first_promo_code,0,1) == "D","Divers", if (substring(first_promo_code,0,1) == "L","Télémarketing", if (substring(first_promo_code,0,1) == "C","Groupeurs", if (substring(first_promo_code,0,1) == "G","Groupeurs", if (substring(first_promo_code,0,1) == "R","Relances", if (substring(first_promo_code,0,1) == "P","Reconduction des contrats en prélèvement", "NR" )))))))))))))))))

Hi,
Instead of hardcoding this mapping in a formula, you should consider creating an editable table, sync that to a dataset and then use a join. With these steps, you would move the logic to the SQL engine.
I hope this helps.
